it's the top of the hour on cnn "newsroom." hello, everybody. >> the united states support for ukraine will never waiver. that's the promise today from president biden. he gave a fiery speech in warsaw, poland. he said the blame lies with russia. he said ukraine stands strong in the face of russian aggression and added that nato stands united, too. >> when president putin ordered ■xhis tanks to roll into ukrain he thought we would rollover. he was wrong. the ukrainian people are too brave. america, you are a coalition of nations from the atlantic to the paw pacific, we were too unified and democracy was too strong. >> president biden spoke just hours after his russian

counterpart railed against the west, and the russian president once again accused the west of escalating the conflict. he also announced russia is now suspending its participation in the start nuclear arms reduction treaty. phil mattingly is in warsaw for us. phil, tell us what the u.s. reaction was specifically to the news from vladimir putin that he was going to suspend his participation in the new start treaty? >> it was a split screen, not one that was planned. that state of the nation address framed everything the president detailed in his lengthy remarks in warsaw. when it comes to what president putin said about the new start treaty, u.s. officials were quick to respond that it would

be irresponsible and compliance wise, russia has not been fully comp compliant over the last few years, and so there's gray area here, middle ground, but it underscores what is the dissolving of the u.s. and russia relationship, and the result of russia's invasion of ukraine, it's a central point of president biden's remarks today. putin thought the west would not come together, and that has been the opposite of what happened and he just pointed to nato itself as an example. take a listen. >> he thought he would get the finalization of nato, instead he got the natoization of finland and sweden.

he thought nato would fracture and divide, and instead nato was more united and unified than ever. >> reporter: the president's reference there to the idea that the nato could be fractured with russia's use of force, instead finland and sweden have applied for membership and are in that process, and one of the elements the president pointed to as clear results of the last month that the coalition stayed together and pointing that the coalition will need to stay together in the days ahead. >> thank you. the senior national correspondent with us. >> victor, as you can imagine, there's across this country a

full throated rejection of the argument putin made before, it was not russia that started the war but ukraine and the west that caused it. putin said today that he was coming in with force to end it, and that, of course, is not the ukrainian point of view. there has been a warm reaction to president biden's speech. we are just hearing from president zelenskyy. will read some of his tweet. he thanked president biden and all of america for their support of freedom and fightvital assis to ukraine. what president biden said here in ukraine yesterday when he was in the capital, that was very well received. reminding the world of the strength and resilience of the ukrainian people and the west and united states' support of ukraine, and putin and his crimes against humanity and for starting the war, and that was

well received. h he's saying it with a lot of credibility in the eyes of ukraine. it's the first time a u.s. president has visited a war zone where there were not u.s. troops on the ground and he spent 24 hours in ukraine crossing the country by train before heading back out to poland. there was a lot in the speech that resinated yesterday and today with ukrainians. perhaps most importantly, that ukraine will prevail in the end, that ukraine must prevail. we heard from the troops and they say they are fighting for the country's very existence, and they cast this battle as a david and goliath fight but that they have the edge because we are fighting for their country's existence. the only thing president biden could have done more was to make more of a material offer. he did that yesterday in kyiv with a $500 million military aid

package. but we saw in his conversations with president zelenskyy that there are still things that ukraine wants and needs for their fight agait russia that the u.s. has not yet been willing to give, namely longer range missiles and fighter jets. ukrainians saying thank you so much for all of your support, we need your continued support but we need more. they would have wanted a little bit more, i think, from biden in terms of the commitment of those more sophisticated systems for this second year of this war against russia. >> it seems to be a cyclical response that we keep hearing and see playing out, the united states and the west offers aid and the ukrainians say thank you and we want more. we do deliver more but they need it right now. thank you. let's bring in william cohen who served as defense secretary under president clinton. mr. secretary, good to see you

again. let's start with putin's announcement of the suspension of russia's participation in the treaty. gauge for us the severity of the impact of this announcement? >> it sends a signal to the rest of the world that the proliferation of nuclear weapons is something the russians prefer and the chinese prefer. the iranians are trying to get that capability. north korea, apparently has it. that sends a signal to other countries that the way forward is to build your own nuclear weapons and that's a danger to awful us. >> you mentioned china. let's talk about china and the top foreign policy adviser to president xi is in moscow meeting with his russian counterpart, and the u.s. state department believes china is

considering escalating, elev elevating its support of russia, and we heard from the u.n. ambassador that would be a redline for the u.s. if china crosses that redline, then what? >> i don't like drawing red lines in public, that we tell or adversaries or potential adversaries behind closed doors. it's serious to us and there will be serious consequences. once you draw the redline in public and the russians start to come closer and closer to the redline, there's pressure on the united states to then enforce it. i think it's already been done as far as the administration is apparently concerned, but nonetheless i think this kind of thing should be done in the negotiating table or a person to person meeting between president biden and president xi. >> china has an interest in seeing what the u.s. response

will be as they look towards potentially invading taiwan and presidenden's mmitment that the u.s. will stand with and defend taiwan at a level it's not defending ukraine right now. but if the redline is crossed, as specific as the administration is, those are likely sanctions. is that enough to convince china not to cross it? can china even be convinced not to cross it? >> we have to work on the relationship with china. china is a big power economically and growing militarily. i think that we need to sit down with the chinese and say, what are the two or three things we can agree upon in order to lower the tensions, because if it continues to go lower and lower, the risk to life on this planet goes higher and higher. for example, it's not something in the japanese mind-set at this

point, but if the north korea's continue to fire icbm's over their territory, they might at some future time decide to go nuclear on their own. what would that pose to china or russia at this point? that certainly would upset the geopolitical calculations. i think the most dangerous point in our world history today, we need to find ways to lower the temperature and the rhetoric as far as what we are going to do and how we are going to do it. that's going to take diplomacy, and i am hoping if president biden and president xi meet, if at all possible, they would try and lower the temperature between our two countries. >> the gratitude from the ukrainians with this additional half billion in assistance including military hardware, they, of course, want the f-16s and fighter jets and longer

range weapons as well. do you believe the ukrainians have what they need? i'm talking in quantity, quality, style, to win, not just to hold off losing or to put up a good fight in what will be a surge in the spring, but to win this war with russia? >> not at this point. they don't have the quantity to be sure. they are getting higher and higher quality capabilities, but they need more. i believe that they will -- ultimately they will get the f-16s and long-range missiles they are looking for. the notion that the russians can fire from long distances whether in the black sea or even from russian territory and then have that as a sanctuary, and that's fundamentally unfair where they are shooting and on their heels defending and you can't fire?

i believe over this period of time, i think the ukrainians are going to have an opportunity to be trained on the f-16s and other type of equipment that will require that kind of advanced training, and they should. >> all right. we have not heard that announcement from the pentagon yet. we will see if it comes. secretary cohen, always good to have you. thank you. in kyiv a day after meeting with president biden, volodymyr zelenskyy shook hands with the delegation of house of representatives, including mike mccall that chairs of foreign affairs committee. he said their visit is more important evidence that the united states supports ukraine. joining me now, the deputy mayor for lviv in western ukraine. thank you for joining us. first, your reaction to the words we heard from president biden today in poland saying the united states would not tire in

its support of ukraine, in the significant speech he made one day after the surprise visit to kyiv? >> it was, indeed, a very inspiring speech, historic. it's a huge impetus and support for all the ukrainian defenders, and all ukrainians inside or outside ukraine. but most importantly, for the rest of the world, f our allies as well, that the united states is with ukraine, and it will stay with ukraine until the end. also, one important comment that he made is the war crimes, the acknowledgment of the war crimes that russia is committing. we heard that also from vice president kamala harris during the security conference. why this is significant is that probably it gives a very clear

message to the kremlin that there's no way for any cease-fire or peace talks except for the accountability that will follow after that. >> we heard a less than inspiring speech today from russian president vladimir putin that seemed to repeat his common phrases that he has been using in the past few years in that russia is the one being on the defense here, and depressed and that the west instigated this and all that he is saying is russia is trying to liberate ukraine. i want to get your response to how he described the current ukrainian government. he called your government a western hostage and you were working in the interest of western governments, in particular the united states, as opposed to the interest of ukrainians. can you address that and respond? >> in ukraine for many months if not years, what has been said

out of putin's mouth or out of moscow is not really taken seriously. russia has never followed their promises. if you follow the social media and responses and the discussions we have here in ukraine, it's many ridiculed -- there was nothing interesting. it was very boring. nothing new -- no new sentences that we have not heard before. all of that is very known. some even call it a kkk speech for the number of comments that putin is known to be making. and what else, what is new that he could have said in the speech? russia is losing. they are definitely knowing that. he shouldn't focus even on discussing this. what we should focus on is what secretary cohen was saying before that, is that all the

world has to continue to be united in solidarity with ukraine, and provide ukraine with the weapons and all the support we need to win the war and win it sooner than later, to save more lives and to have less damages and casualties. >> national security adviser said, quote, seeking a common understanding for what the objects are for ukraine going forward. what are the current objectives in the war? is it to go back to the borders of february of last year, or back to the 2019 borders? >> it's been clear, and there's a consensus now and we are happy to see that consensus, and also among over 50 members of the

solidarity group and allies behind the ukrainians, and these are the countries that control two-thirds of the global gdp that only they return to the 1991 borders will signify a victory and road to peace. this is a well known and publicized peace formula presented by the ukrainian president a few months ago, which is now supported in the majority by the world leaders. >> finally, let me ask you as we are hearing reports that the u.s. intelligence has picked up china is contemplating providing russia with weapons, and what is your position as they are contemplating providing weapons to russia? >> my message would be to

continue to be beijing, continue to be china, as it has been for thousands of years. china should stay and mind their own business and national interests and continue to promote peace and security throughout the world, at least the narrative they have been speaking about for years. they should be staying out of this potential support to russia. i think the american side and many other countries have already made pleas to china, and let's be clear, it's dependent on trade and relationships with the european countries and the united states, the business and economic development. that escalation by supplying lethal weapons to russia will lead to crossing the redlines

for the chinese future. >> thank you for your time. big tech and national security. details on the case between google and the family of an isis victim that made its way to the supreme court. in south carolina, the defense called alec murdaugh's only surviving son to the stand. his testimony just ahead. ♪ customize and s save. ♪ only pay for what you u need. ♪ liberty. liberty. liberty. liberty. ♪ one role of a lilifetime... one sore throat. but she had enough. she took mucinex instasoothe sore throat lozenges. show your sore toat who's boss. mucinex instasoothe. works in seconds, lasts for hours. sometimes you're so busy taking care of eryone else you don't do enough for yourself, or your mout but eventually, it wl remind you. when it does, aspen dental is here for you. we offer the custom dental treatments you need, all under one roof, right nearby.

proven quality sleep. only from sleep number. right now the supreme court is hearing a case that could have a major impact on the future of the internet. the family of the only american killed in the paris terror attack in 2015 is suing google. they are arguing the company promotes and profits from extremist content posted on youtube. a decision against google would have sweeping implications on the liability shields that so far protected big tech platforms from lawsuits. >> these are not, like, the nine greatest experts on the

internet. and i don't have to -- i don't have to accept that the sky is falling stuff to accept something about, boy, there's a lot of uncertainty about going the way you would have us go, in part just because of the difficulty of drawing lines in this area, and because of the fact that once we go with you, all of a sudden we are finding that google is not protected, and maybe congress should want that system. isn't that something for congress to do and not the court? >> you think that's a question we hear consistently out this court? a supreme court analyst and a cnn reporter, welcome. you sat in on today's oral arguments. what is your sense of how the justices are approaching this case? >> good afternoon, breonna and victor. you plucked out one of the rare

moments of levity during the three-hour session. the frustration in the room was palpable. the justices have taken this case to find out if there have been new liability for places like google and youtube and other social media companies for third party content. but things that are ranked and recommended by those sites, they ran up against a wall of just a lot of confusion. they said they were seeking more clarity on where to draw lines and a fundamental question, as you said, is shouldn't this be something for congress, for policymakers rather than for the justices. if they rule broadly here, could it open the door for more lawsuits? the case involved section 230 of the communications decency act that says no provider of interactive computer services should be considered a publisher, and the question is if they start to have new liability how far will that go. i should say there's a part two

coming, a sequel, tomorrow where twitter will be before the justices and that case will test an anti-terrorism act and the question will be whether some terror videos that were on twitter and other sites, whether those terrorism videos would give liability under this anti-terrorism act. one thing i should say, if the justices find that anti-terrorism law doesn't apply and that covers sites that would have knowingly aided and abetted terrorists groups, it could affect today's case and the justices might not go towards looking at any kind of change in section 230 of the communications decency act. >> joan, it's interesting that you highlight the sound bite we picked. justice kagan started that the

justices are not the experts on the internet and isn't this something congress should do, and we have seen members of congress are not the experts either on the internet, so there's a bit of discrepancy and a deficit, i should say, as well. let me come to you, brian. the concerns that the big tech companies have about this lawsuit if the justices agree with the plaintiffs, what are they? >> well, victor, there are two issues here. one is, as joan mentioned, the potential increase in lawsuits targeting the tech industry. even if many of the lawsuits are thrown out, just the expense of having to fight them constantly, and many could be brought in bad faith, and could potentially sink many in the tech industry. the second issue is how -- how do these lawsuits change the way

that tech companies avoid liability by changing the way they moderate their platforms? that could mean, you know, if things as simple as up votes or down votes or comments or likes and retweets are considered recommendations, that could mean, you know, real changes to the way that users experience these websites. by the way, it's not just big tech that stands to be affected by this. you have justice amy coney barrett asking questions repeatedly throughout this three-hour long oral argument about how these changes, if they go into effect or if the court decides to make the changes, how it could change for individual internet users. could i be open to a lawsuit if i hit like or a retweet on a tweet? the attorney for the gonzalez family acknowledged, yes, in his view and his interpretation of section 230, that's what could

happen, internet users, individuals could face liability for sharing other content. >> yeah, there could be a lot on the line for not just the companies but those that use it. thank you both. an elderly woman in florida was killed by an 11-foot gator. how did this happen? we'll tell you, ahead. hold on... you're a night manager and mom, and the bill payer, baker, and nightlight maker? that's a lot. so, adding “and stude” might feel daunting. but what if a school could be there for all of you? career, family, finces and mental health. -happy birthday! -happy birthday buddy. well, it can. national university. supporting the whole you.

florida wildlife officials are investigating the death of an elderly woman dragged into a pond by an alligator that is close to 11 feet long. >> leyla, give us the details. how did this happen? >> reporter: we now have the incident report from fish and wildlife. we are getting more of the details of what led up to this and how it happened and who was involved. we have now learned it was an 85-year-old woman by the name of gloria surge. she was walking her dog over on the edge of a pond that was right behind her house, and as you mentioned there was an alligator described by the sheriff as an 11-foot alligator -- give me one second here. okay. can you hear me okay? >> we got you. >> you're in and out, yeah. >> okay, can you hear me okay? >> we hear you.

>> reporter: you can hear me okay? >> yeah. >> reporter: okay. i understand there was audio issues, so i will go back to what we have learned since we had the incident report from fish and wildlife, it was an 85-year-old gloria surge that was walking her dog along the pond behind her home, and in that moment an 11-foot alligator, a big, big alligator in the images we have shown you, that alligator came out and tried to go after the dog. in that moment surge was knocked down and she was pulled into the pond and died. as you might imagine, horrifying moment for neighbors. listen to how they described it. >> it's scary. that's really scary. they are around here, they move

from pond to pond. >> it's my understanding he attacked the woman and it's my understanding she died. i wanted him out of here and euthanized. >> reporter: the alligator was, in fact, caught and euthanized according to fish and wildlife. fish and wildlife was quick to point out that it was horrifying, and it's also something that remains very rare. across 67 counties in arizona you are talking about 1.3 million alligators, so it's something common for people in florida to see. why fish and wildlife is stressing the protocols, not to feed the alligators and keep your distance. >> having lived in florida for seven years, this is something you hear every few years and when you hear those numbers you understand it's a rare tragedy,

nonetheless. thank you for the report. >> thanks. today in the double murder trial of alex murdaugh, the former south carolina's attorney's only living son took the witness stand. >> they are trying to attempt to paint the attorney as a loving father and husband. what did he tell the jury? >> reporter: hello to both of you. this is the first murdaugh family member to testify, and they talked about evidence, including the shotgun that palmepaul murdaugh was killed with. he testified nobody in his family, which would include his father, would ever load the weapon with a buckshot and bird shot.

clothes. none of the lawyers asked buster murdaugh if his father was capable of this, if he might do something like this? nobody asked that directly. he talked about what a loving family it was, but was never asked that directly. f >> thank you. united airlines with a new family seating policy. details, next. ♪ what will you do? will you make something better? create something new? our dell technologies advisors can provide you with theools and expertise you need to bring out the innovator in you. think he's posti about all that ancient roman coinage?

new today the biden administration just announcing a major rules change for asylum seekers. >> it would impact people trying to reach the u.s. through other countries including mexico. cnn white house reporter, sylvia alvarez is here with details. what do you know? >> this is the most restrictive measure the administration has taken so far trying to manage the u.s./mexico border. they told report kwers they havo take the steps to manage the mass migration. first of all, u.s. law permits migrants seeking asylum to do so regardless of how they arrived on u.s. soil. what this rule would do is presume ineligibility based on how they arrive. if they pass through multiple countries on the way to the

u.s./mexico border but did not seek refuge in those countries, then they are not eligible. there are exceptions, of course, and what the administration is trying to do here is have migrants apply for lawful pathways to the united states, including some of the programs they recently rolled out for certain nationalities that allows them to come for a temporary period and apply for asylum once they are in the united states. for example, this was the case for venezuelans and cubans and nica nick raug. in the interim, they will have to take measures to try and manage the flow of migration, especially looking on the horizon when they may lose the border restriction known as title 42 that allows authorities

to turn migrants away. that's still part of litigation. when that is to help, they say these are the measure that will help them. >> thank you so much. health experts are warning that there's a shortage of black doctors right now, which will have a direct and negative impact on the country's public health. we'll explain how after the break. for r a beautiful mattress, and indescribable comfort. for a limited time,, save up to $800 on select stearns & foster® adjustable mattresses sets. hey, man. you could save hundreds for safe driving with liberty mutual. they customize your car insurance. so you only pay for what you need! whoo! we gotta go again. only pay for what you need. for adults with generalized myasthenia gravis who are positive for acetylcholine receptor antibodies, it may feel like the world is moving without you. but the picture is changing, with vyvgart. in a clinical trial,

to make sure our doctor workforce reflects the diversity seen among patients. >> we need to do more because we've discussed this before the benefits of the more diverse workforce often sometimes doctors will dismiss the concerns or symptoms of a certain demographic, explain what study shows. >> exactly. research shows when we have a diverse physician workforce there's more understanding and trust between the patient and the doctor. the doctor has an understanding of the patient's cultural experiences, cultural background, lived experience, especially when it comes to racism or discrimination or other aspects of their life, that can help with that physician-patient relationship. we also see that patients are more likely to follow a physician's medical advice if they have a feeling of being heard and understood. all this plays a role in improving public health. >> jaclyn howard, thank you so

muntean here's to explain how this will work. some want the kids to sit in row 31. >> depends on how old the kids are. >> okay. but tell us about this plan. >> some people want their kids next to them. and that's the big deal here. because when you travel as a family, you know, families complain about this a lot and it's a huge priority for the biden administration and now it's sort of becoming one for the airlines, you know, the issue here is that they would have to essentially plead at the gate or ticket counter to try to make it so that you can sit next to your kid essentially free of charge. what united is doing here is putting out a seat map if you book a base economy ticket you can sit next to your child under 12 no charge. all of those seat selection fees can add up. think about it if you're flying with a family, two three, four kids, really piles on, on top of the, the existing ticket price.

the biden administration says the airlines tack on all of these fees, especially when it comes to baggage, seat selection, they say that you just can't treat family members like baggage. and that's almost the exact quote that president biden used during his state of the union address when he was addressing these junk fees, not only in the airlines industry, but also across so many industries. want you to listen to that now and how impassioned he was about this problem. >> we'll prohibit airlines from charging $50 round trip for families just to be able to sit together. baggage fees are bad enough. airlines can't treat your child like a piece of baggage. >> think about this. on some airlines you might have to get charged $139 as much on american airlines to choose your seat as much as $200 on some budget carriers like spirit airlines. consumer advocates say this is a great start but the federal government needs to take this one step further and enact a law

to make it so that airlines cannot charge you extra if you want to sit next to a young family member. it's a big development here. although consumer advocates say maybe not enough just yet. >> pete. of course victor was kidding. he would never want to separate families on airplanes. >> i'm not looking to separate families but if you want to be separate from your family you should have the option. just saying. >> that's a different airline. >> all right. thank you so much. "the lead with jake tapper" starts right now. >> president biden says ukraine will never be a victory for russia. "the lead" starts right now. two world leaders two different messages a nato rallying cry for biden while putin blames the
